I don't think this is really needed - it doesn't hold any state that can't just
be fetched each time in UpdateAppMenu(). The only bit that really feels
heavyweight is generating the app_id/taskbar group, and this isn't specific to
JumpListUpdater, so it probably belongs here instead. (i.e. replace this data
member with `wstring taskbar_app_id` or similar)

I think if we introduce a ~"modify jumplist" API then we will need some extra
state, but it shouldn't be windows-specific (i.e. would go on a parent class,
and be more generic).
